Title: Fine edged cutting implements and the manufacture thereof
IPC: B26B21/60
Filed: 1943-05-15
Abstract: 565,640. Depositing substances by electric discharges. KAYSER, J. F., and GILLETTE INDUSTRIES, Ltd. May 15, 1943, No. 7776. [Class 39 (i)] [Also in Groups II and XIV] The edges of safety razor blades or other fineedged instruments are, after being sharpened, protected against corrosion by an adherent coating of one or more metals deposited on the edges by the cathodic sputtering or evaporation film producing methods. The deposited metal may be gold, but a harder metal such as rhodium nickel or chromium may be used to protect the edges from abrasion as well as corrosion. In the cathodic method, the flow discharge is preferably produced by a direct potential of 2000 volts, the residual gas in the chamber being air and the cutting edges being parallel to a disc-like cathode. The residual gas may be argon or hydrogen. The low pressure in the chamber may be obtained by a fast pump, the chamber being continuously washed by air or hydrogen. In the evaporation method, the edges may be exposed to the molecular rays emitted by a piece of the coating metal when heated until its vapour pressure is about 10<-2> mm. of mercury. In both methods, the blades may be heated to a temperature not substantially exceeding 200‹C. The blades may be coated while in strip form or after severing into individual blades. The body as well as the edges may be similarly coated.

Patent GB-357933-A (GB)
Title: Process for the production of bleaching powder
IPC: C01B11/06
Filed: 1931-03-14
Abstract: Bleaching powder is obtained by chlorinating hydrate of lime in the presence of an inert readily vaporizable liquid namely carbon tetrachloride, chloroform or mixture thereof, which is present in amount varying say from 3-7 per cent, so that the pulverulent condition is continuously retained.  The heat of the reaction is absorbed in evaporating the liquid, whereby the temperature does not rise sufficiently to cause caking of the product.  The process may be effected in a stirring apparatus; this may be closed, the vaporized liquid being condensed on the walls, or the vapour evolved may be led to a condenser, and fresh liquid continuously supplied.  Carbon tetrachloride may be expelled from the product by treatment in vacuo at 30-40 DEG  C., or with hot air.
